Security News > 2020 > April > Firefox, IE Vulnerabilities Exploited in Attacks on China, Japan

Vulnerabilities patched earlier this year in Firefox and Internet Explorer have been exploited by an advanced persistent threat actor in attacks aimed at China and Japan.
Both vulnerabilities were exploited in attacks before patches were released.
A blog post published in February by Chinese cybersecurity firm Qihoo 360 revealed that both security bugs were exploited as part of the same campaign aimed at Chinese government agencies.
Japan's Computer Emergency Response Team Coordination Center has reported seeing attacks on Japanese entities exploiting both CVE-2019-17026 and CVE-2020-0674.
In a blog post published on Thursday, JPCERT said targeted users are taken to a website set up to deliver Firefox or Internet Explorer exploits depending on the victim's browser.
